Hi all. First of all this is a great site. Thanks to all for sharing such a knowledge and experiences. I am 26 yrs old male very active and workout 5 days a week. I lift weights and am in really good shape. All of a sudden since last September, I feel dizzy, persistent headaches, neck pain, jaw pain. My quality of life has gone down. I was referred to neurologist and was diagnosed as migraine. I do not think so but they ordered MRI, CT scan to rule out MS.The results were negative and then the migraine medicines sis not help too. I can hear heart palpitations in my head and stomach.You can see the heart palpitations by placing mobile phone on my stomach. Doctors diagnosed it as high blood pressure. I was on medication. I did not believe it and bought a machine to check and kept a note of the reading for 2 months. I do not have BP at all. Then they have hook up a heart monitor for 1 month. They said that my heart rate is only 48 per minute. After 30 days they say everything is fine. I believe it is due to my cardio workout 5 days a week. Then started my knee pains. Then my shoulder. It has become so bad that I cannot raise my arm after certain height. Then my rib cage at certain points. My doctor say it is just inflammation. Then started acid reflex. They have done endoscopy, ultrasound, X-ray for knees. Now my lower back, elbows, tendons started paining. My doctor says that I have fibromyalgia. I did not believe it either. They also say that I have TMJ for jaw pain. I think this is all crap as I am so active and healthy and how all of a sudden I get so many diseases. I asked my doctor for Vit D test after looking over internet for bone and muscle pains and she said that my calcium is 10 mg/dl and I do not need Vit D test. After I insisting she has ordered for it and the result is 7 ng/ml. I am on 50000IU pill a week. She says that Vit D has nothing to do with these symptoms. My head aches got much better and dizziness too. neck pain is Okay. My shoulder, knee and upper ab still hurts. Just after 1 month of dosage I got it rechecked and the value is 48 ng/ml. I am drinking almost 900 ml - 1 liter of milk every day too (thanks I can tolerate dairy). But the value got up so much in 3 weeks for me where as others say it took 3-4 months? Do you think the tests were right? Also, do you think these have something to do with vit D def? Do I need to get any other tests done? I got my parathyroid and thyroid and they look okay. PTH came about 50 pg/ml. TSh came out 1.07 uiU/ml. My calcium came down by .2 points and is 9.8 mg/Dl when my vit D came up to 48 from 7 in these 3 weeks. Please suggest if I need to get any other tests done. I am planning on changing my PCP.
